Deforestation and Efficiency: Insights From Forest Transition in the Brazilian Cerrado

open access: yesAgribusiness, EarlyView.
ABSTRACT This paper estimates technical efficiency (TE) and environmental efficiency (EE) of agricultural production at the municipal level of the Brazilian Cerrado in 2006 and 2017, and investigates their underlying mechanisms in relation to forest transition theory.

Assessments of recent tundra change based on repeated vegetation surveys

open access: yes, 2010
Results from experimental warming studies suggest tundra vegetation will respond rapidly and dramatically to climate warming, and indeed, NDVI data from remote sensing and repeat aerial photography suggest such changes may already be occurring.

Stochastic Locomotion Emerging From Body–Environment Interactions in a Mexican Jumping Bean–Inspired Robot

open access: yesAdvanced Intelligent Systems, EarlyView.
Inspired by the Mexican jumping bean, this study presents a centimeter‐scale, electronics‐free robot that merges principles from both the animal and plant kingdoms. A thermo‐responsive actuator mimicking larval motion, enclosed within a uniquely shaped plant‐seed‐inspired shell, generates jumping, rolling, flipping, sliding, and climbing through ...

Climate and vegetation change effects on the distribution of the narrow-species Santolina ligustica

open access: yes
In this study, we used historical distribution data, SDMs, NDVI and land-cover patterns to unravel the relative role of climate and vegetation changes in determining the distribution of S.
